Our MH LPG tank has a manual screw type vent valve that, when in a vent (filling) position, will spew the liquid propane at 80% full. There is no such feature on any portable LPG bottles that I am aware.
The "spit" valve in a portable propane "tank" does the same thing. It vents liquid propane when the "tank" is full, just as the permanently mounted ones in a MH do. The exact method they use use is slightly different, but the result is the same.
Yep....bleeder valve
"....the attendant may open the bleeder valve, reset the meter and begin pumping propane into the bottle. The attendant will stop the pump once:
The bleeder valve starts to spew liquid
The scale indicates the cylinder has reached its legal filling capacity
The OPD valve stops the flow of propane into the cylinder (if equipped with an OPD valve)"
